MATRIX FOR LINE-CASTING MACHINES.

Specification of Letters Patent. Application filed June 9, 1910.

Patented Sept. 22, 1914. Serial No. 585,953.

To (ZZZ whom it may concern Be it known that I, HUGH ALFRED SPAR- Fgreater widths, that is to say, with wider LING Of New Orleans, parishof Orleans,- and State of Louisiana, have invented a! of which the Qlike between adjacent matrices when asj in actual practice, and

thaler liuotype machine of the general 'organizaticurepresented inLetters Patent of the United States No. 436,532. These matrices,representing individual characters, are carried in a magazine, fromwhich they are delivered one at a time by a fingerkey mechanism, thereleased matrices being assembled temporarily in line and presented to amold to form type characters on a slug cast therein, after which thematrices are returned through a distributing mechanism to the magazine.Each matrix consists 'of a flat rectangular piece of metal having in theupper end a notch containing distributer teeth, and having on the twovertical edges projecting ears or shoulders at the upper and lower ends;These ears or shoulders, which engage with various parts of the machineto sustain and aline the matrices, also travel in the guiding grooves orchannels in the magazine plates. In passing downward from thedistributer into the upper end of the magazine certain of the matricespursue latenally curved paths. hen very large or thick matrices areemployed the space or; clearance at their sides -is very slight, and itis found that if the. matrices are made with the usual straight parallelears and upper ends of full thickness they occasionally bind in thechannels against one another so that is retarded or arrested.

My invention is designed to overcome this difficulty, and to this end itconsists in a matrix having its upper end, including its upper ears,beveled or ch amfered, whereby it is reduced in thickness at one end. Inthis manner I am able to retain all the features and proportionsnecessary for the proper handling of a matrix at the various points inthe machine, while at the same time I am enabled to handle matrices ofand their advance guiding surfaces,

characters, than heretofore, without difficulty.

Another valuable advantage arising from my improvement is the facilitywhich it gives for the insertion of spaces and the sembled. Thisnecessity frequently arises particularly in connection with tabularwork, when the beveled or. chamfered upper edges of the matrixpermitsthe ready insertion and seating of the spaces or blanks.

In the drawings: Figure 1 is a perspective view of one of my matriceslooking toward the front or inactive edge. Fig. 2 is a. perspective view'of the same looking toward the active end, containing the character ormatrix proper. Fig. 3 is an edge view. Fig. 4 is a side view.

Referring to the drawings, A represents the body portion of a matrix,consisting of a flat, generally rectangular plate having parallelvertical edges, one of which contains the intaglio character or matrixproper, a.

a, c of and a represent ears extending edgewise from the matrix at theupper and lower ends, these ears serving to enter the groove or channelin the magazine plates for the punpose of guiding the matrices, and

also serving to engage with the various members of the machine by whichthe matrices are alined, distributed and otherwise controlled.

The upper end of the matrix is formed with a V-shaped "notch havingdistributing teeth a therein.

So far as described the matrix may 'be-in all respects of ordinaryconstruction;

I Her'etofore it has been customary to construct all the ears of thesame thickness, and with parallel Vertical faces. length of the upperears is such chines of ordinaryconstruction possible for these cars tofollow the curved paths required in entering the magazines from thedistributor without binding on the or conflicting with adjacent matricm.In order to overcome this difliculty I bevel, 0r chamfer, the upper endThe.

it was irrl- I of the matrix, including the upper ears a and (L in anupward and backward direction, thus reducing the thickness of the uppercars and of the upper end of the matrix, as'shown in the severalfigures. When thus formed the matrix will follow the various pathsrequired freely and speedily, and without conflicting with othermatrices. Although the ears are reduced in thickness at the upper endthey are left of the ordinary or full'thickness at the lower ends, orpractically so. Their under faces or shoulders, by which the matricesare sustained and alined, remain unchanged. In short, all those surfacesof the ears heretofore employed, and which are necessary for the properguidance and adjustment of the matrices in their course through themachines, are retained.

When the matrices are of very great thickness I prefer to bevel orchamfer the lower ends as shownat a, this ohamfer being on the oppositeside to that at the upper end. This feature is old in itself but whencombined with the chamfer at the upper end it gives a matrix such formthat it may be handled with rapidity and certainty by the ordinarymechanisms of the machine.

Having described my invention what I claim is:

l. A matrix adapted for circulation in a typographical machine andbeveled or chamfered at its upper end to facilitate its guiding duringcirculation.

2. A matrix adapted for circulation in a typographical machine andformed on its edges with guiding ears, the said ears being beveled orchamfer'ed at their upperends to facilitate the guiding of the matrixduring circulation.

3. A matrix adapted for circulation in a typographical machine, andbeveled r chamfered at both its upper and lower ends to facilitate itsguiding during circulation.

.In testimony whereof I hereunto set my hand this th day of May, 19-10,in the presence of two attesting witnesses.

H. ALFRED SPARLING.
